DMX data link
The MAC Encore™ Performance has 5-pin locking XLR sockets for DMX and RDM input and output (see
Figure 8 on page 11). The default pin-out on both sockets is:
• pin 1 to shield
• pin 2 to data 1 cold (-)
• pin 3 to data 1 hot (+).
Pins 4 and 5 are not used by the fixture but are bridged between input and output sockets. These pins can
therefore be used as a pass-through connection for an additional data signal if required.
Tips for reliable data transmission
• Use shielded twisted-pair cable designed for RS-485 devices: standard microphone cable cannot transmit
control data reliably over long runs. 24 AWG cable is suitable for runs up to 300 meters (1000 ft). Heavier
gauge cable and/or an amplifier is recommended for longer runs.
• To split the data link into branches, use one of the splitter-amplifiers available from Martin® (see under
"Accessories" in the product specifications given at the end of this document.)
• Do not overload the link. Up to 32 devices may be connected on a serial link.
• Install a DMX termination plug on the last fixture on the link.
Connecting the data link
1. Connect the DMX data output from the controller to the MAC Encore™ Performance's data input (male
XLR) socket.
2. Run the data link from the MAC Encore™ Performance's data output (female XLR) socket to the data
input of the next fixture.
3. Terminate the data link by connecting a 120 Ohm, 0.25 Watt resistor between the data 1 hot (+) and cold
(-) conductors (and between data 2 hot and cold if used) at the data output of the last fixture on the link.
If a splitter is used, terminate each branch of the link.
